THE SECRETARY OF THE NAVY WASHINGTON The President of the United States takes pleasure in presenting the PRESIDENTIAL UNIT CITATION to the FIRST MARINE DIVISION, REINFORCED for service as set forth in the following CITATION: “For extraordinary heroism in action against enemy aggressor forces in Korea during the periods 21 to 26 April, 16 May to 30 June, and 11 to 25 September 1951. Spearheading the first counteroffensive in the spring of 1951, the First Marine Division, Reinforced, engaged the enemy in the mountainous center of Korea in a brilliant series of actions unparalleled in the history of the Marine Corps, destroying and routing hostile forces with an unrelenting drive of seventy miles north from Wonju. During the period 21 to 26 April, the full force of the enemy counteroffensive was met by the Division, north of the Hwachon Reservoir. Although major units flanking the Marine Division were destroyed or driven back by the force of this attack, the Division held firm against the attackers, repelling the onslaught from three directions and preventing the encirclement of the key center of the lines. Following a rapid regrouping of friendly forces in close contact with the enemy, the First Marine Division, Reinforced, was committed into the flanks of the massive enemy penetration and, from 16 May to 30 June, was locked in violent and crucial battle which resulted in the enemy being driven back to the north with disastrous losses to his forces in the number of killed, wounded and captured. Carrying out a series of devastating assaults, the Division succeeded in reducing the enemy’s main fortified complex dominating the 38th Parallel. In the final significant offensive of the action in Korea, from 11 to 25 September 1951, the First Marine Division, Reinforced, completed the destruction of the enemy forces in Eastern Korea by advancing the front against a final desperate enemy defense in the ‘Punch Bowl’ area in heavy action which completed the liberation of South Korea in this locality. With the enemy’s major defenses reduced, his forces on the central front decimated, and the advantage of terrain and the tactical initiative passing to friendly forces, he never again recovered sufficiently to resume the offensive in Korea. The outstanding courage, resourcefulness and aggressive fighting spirit of the officers and men of the First Marine Division, Reinforced, reflect the highest credit upon themselves and the United States Naval Service.” The following reinforcing units of the First Marine Division participated in operations against enemy aggressor forces in Korea during the cited periods:
